Method and device for processing routing status and/or policy information

A method for processing at least one of routing status and policy information, comprising:

• sending, by a Software Defined Network (SDN) control client, a third request for establishing a connection, wherein the third request carries an identifier of the SDN control client, the identifier is used for establishing a corresponding relationship between the SDN control client and at least one of routing status and policy information at a routing or forwarding system side;
• after the routing or forwarding system establishes the connection with the SDN control client, sending, by the SDN control client, at least one of routing status and policy information to the routing or forwarding system;
• wherein the third request further comprises a priority of the SDN control client, wherein the priority is used for marking at least one of the routing status and policy information at the routing or forwarding system side, to make the routing or forwarding system handle the conflict according to the priority marked on at least one of the routing status and policy information, when a plurality of SDN control clients have a conflict in operating at least one of the routing status and policy information.

A device for processing at least one of routing status and policy information, which is located at a Software Defined Network (SDN) control client side, comprising:

• a first sending component to send a third request for establishing a connection, wherein the third request carries an identifier of the SDN control client, the identifier is used for establishing a corresponding relationship between the SDN control client and at least one of routing status and policy information at a routing or forwarding system side;
• a second sending component to send at least one of routing status and policy information to the routing or forwarding system after the routing or forwarding system establishes the connection with the SDN control client
• wherein the third request further comprises a priority of the SDN control client, wherein the priority is used for marking at least one of the routing status and policy information at the routing or forwarding system side, to make the routing or forwarding system handle the conflict according to the priority marked on at least one of the routing status and policy information, when a plurality of SDN control clients have a conflict in operating at least one of the routing status and policy information.
